7 Claims.

This invention relates to the manufacture of round-section chenille yarnfrom chenille yarn having radial tufts.

I An object of this invention is to provide an improvedmethod and meansfor curling the radially positioned threads of chenille yarn by firstmechanically compacting the threads into a curled form of much smallerdiameter, and then subjecting the round chenille to an ironing treat-Another object of this invention is to provide means for continuouslyimparting a partially compacted and spirally curled form to a chenilleyarn, comprising an elongated tube having a cc-nicalinlet end and havinga conical thread in said inlet end, the said elongated tube havinganinner diameter corresponding to the smallest.

diameter of the conical inlet and in providing -rueans torn-eating thesaidtube and meansfor rotating the heated tube.

Another object of this invention is to provide f means for frictionallyrestraining and tcnsioning chenillelyarn against rotation at theentrance into said conical inlet and in providing means for pullfeedingthe chenille yarn at the exit end of the .said tube, the said tensioningand feeding With the above and. other objects in view, the

invention will be hereinafter more particularly described, andthecombination and arrangement of parts will be shown inthe accompanyingdrawing and pointed out in the claims which form part of thisspecification.

apparatus shown in Figure 3. I

FigureS is a cross-sectional view of amodified.

a feeding movement tube having a portion of its length threaded, thethread being a continuation of the thread in the conical inlet to thetube.

In the illustrated embodiment of the invention, the numeral it indicatesan elongated tube having an integral conical inlet. I I. The inlet I ihas a conical thread I2 throughout its length. I

The tube ill has been rotatably mounted in ball bearings it carried inbearing supports M. A pulley it fixed to the tube It is driven by a beltIt and causes rotation of the tube.

The rotatably mounted tube Ill is enclosed by a. stationary electricalheating unit I? having a l:1ighresistance wire It; An electric currentpassing through thehigh-resistance wire causes the wire to get hot andto heat the heating unit ii and the tube it. I

The bearing supports I4 and the heating unit Il may be secured to a baseI9. Secured to the base are spaced supports 20 having eyelets 2i inalinement with the axis of the tube Ill.

Secured to the base at the outlet end of the tube i0 is a bearing. 22having a shaft 23 rotatably mounted therein. A roller 2% has been fixedt0 the shaft 23. Supported by an extension 25 of the bearing 22 is acarrier 26 having an elongated vertical slot 2'l. A roller 28 has anintegral axle 29 journalled in the slot 27 and is thus adapted forvertical motion to and from the roller 24. v

A gear Ell fixed to theshaft 23 and driven in any suitable manner indirection of the arrow,

causes rotation of the roller 24 and the superposed therethrough. I

The yarn 3! after being passed through the eye'- lets is pulled throughthe conical inlet I I and out of the tube l-EI and around the rollers 24and 289 The roller 28' has considerable weight and causes a frictionaldrag tobe exerted on the yarn passing therebetween. When the gearilllrotates the shaft23 and the attached roller 24, a pullfeeding actiontakes place and the yarn is congagement with the radial threads 33 andgradually curls the said threads in spiral form and compresses them to amuch smaller diameter corresponding to the internal diameter of the tubeH]. The partially compacted and curled yarn in passing through theheated portion of the tube it] is ironed and assumes a permanent set andso that the chenille yarn in the said form 34 is of the same diameterthroughout and has finely curled threads. 7

It is to be noted that the rotation of the threaded tube I0 must be inthe direction of the,

twisting of the core 32 of the chenille yarn 3|.

The temperature of the heating unit I! is regulated to suit theparticular yarn worked upon.

It is essential that the pull-feeding mechanism shall be geared to pullthrough the tube a length of curled chenille yarn exactly correspondingto the length of tufted chenillebeing curled and fed by the screwthreaded conical inlet I I.

In accordance with the patent statutes I have described and illustratedthe preferred embodiments of my invention, but it will be understoodthat various changes and modifications can be made'therein withoutdeparting from the spirit of the invention as defined by the appendedclaims.

I may utilize the modified heating or ironing tube shown in Figure 5,the said tube having an internal screw thread 35 for a portion of itslength and forming a continuation of the thread in the conical inlet tothe tube.
